This is a narration of a video clip of the North Tower of the World Trade Center which focuses on explosive ejections progressing in waves down the faces of the building under the canopy of falling debris. Observation is the foundation of science.
North Tower Exploding
The starting point in science is observation.
What you are seeing here is what happened to the North Tower of the World Trade Center, the second of three buildings to collapse on 9/11 2001. I use the word "collapse", but words can be deceptive.
What do you really see happening here?
There's a tremendous amount of falling debris, but under the canopy of debris, do you see the rapid sequence of explosive ejections of material? Some of the jets have been clocked at over a hundred miles per hour. I will call them explosions because it's hard to find other words that describe what we are seeing here.
The explosions are not isolated and few. They are continuous and widespread. They move progressively down the faces of the building keeping pace with falling debris. Perhaps you can imagine a natural cause, but I can't.
Notice there are explosions far below the point of collapse. Some are isolated and focused; these are often referred to as squibs, and are commonly seen in controlled demolitions.
However, this is not a standard controlled demolition. The building is being progressively destroyed from the top down by waves of explosions creating a huge debris field.
Slabs of concrete did not fall to the ground and smash to dust. There is almost no concrete in the rubble pile. Notice that the concrete is being forcefully ejected outwards from the sides of the building, already pulverized to dust.
What could hurl heavy girders with such force and give them such speed? Some people have suggested that the weight of the tower crushing down on the girders cause them to flex and they sprung sideways by a spring action. But we are not seeing isolated jumping girders. We're seeing a major fraction of the mass of the building, steel, concrete, office furniture, and the remains of human beings reduced to small pieces of rubble and fine dust, and being explosively ejected in all directions.
Bone fragments are found on the roofs of adjacent buildings. The bones were not crushed in the falling mass or they would have been trapped in the debris pile. They were pulverized along with everything else and blown out in all directions.
The NIST investigators have claimed that the top section of the building above the plane impact point came down like a pile driver crushing the undamaged lower section of the building all the way to the ground. The top section of the building is, however, noticeably absent; there is nothing above the ring of explosions except for a fountain of debris.
Can you see a pile driver?
It does not appear that the building is being crushed by anything. The waves of destruction and explosive ejections of material are occurring over a wide zone that continues all the way to the top of what remains of the building.
The scientists at NIST did not model the collapse of the towers. Their analysis was gravely flawed in many ways, but the biggest flaw was that the scope of their investigation was artificially limited. They took their analysis only to the point of initiation of collapse as though all that followed was inevitable and needed no explanation.
The scope of their investigation was artificially limited to what might have happened or could have happened to begin the collapse. What they explicitly did not take into account is what actually happened. By limiting their investigation to the natural precursors of collapse, plane damage and the fire, they ruled out from the start any possibility of discovering evidence of planned demolition. In other words, anything that occurred during the collapse itself, such as the evidence you're seeing here, was explicitly scripted out of the investigation.
Any analytical model of the collapse, no matter how simple or how sophisticated, is a bad model and bad science if it does not come back full circle to explain the actual observations.
